Western blot - C1s antibody (ab66762)
Anti-C1s antibody (ab66762) at 1 µg/ml + Human Plasma Total Protein Lysate at 10 µg
Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
developed using the ECL technique
Performed under reducing conditions.
Predicted band size : 76 kDa
Observed band size : 90 kDa (why is the actual band size different from the predicted?)
Additional bands at : 65 kDa. We are unsure as to the identity of these extra bands.
Exposure time : 3 minutes
The Complement C1s subcomponent protein contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
Immunocytochemistry/ Immunofluorescence - C1s antibody (ab66762)
ICC/IF image of ab66762 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab66762, 1µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 100% methanol fixed (5 min) HepG2 and MCF7 cells at 1µg/ml.
